Bacopa Caroliniana
Bacopa caroliniana
Plantae›Tracheophyta›Magnoliopsida›Plantaginaceae
📍 South America
Bacopa caroliniana is a robust, easy-going stem plant with rounded, fleshy leaves arranged in whorls along upright stems. Under high light the leaves develop a golden to pale-pink tinge; under low light they remain mid-green. It has a distinctive lemon scent when leaves are crushed. A reliable background or mid-background plant for community tanks and an excellent beginner stem plant that tolerates a wide range of conditions.
Tank Mates
Peaceful algae-eaters that will not damage plant leaves and help maintain tank cleanliness
Small, peaceful community fish that provide gentle bioload and won't uproot or consume plant tissue
Beneficial invertebrates that graze algae without damaging healthy plant leaves
Peaceful mid-water swimmers that coexist well with stem plants in community setups
Bottom-dwelling catfish that aerate substrate and won't disturb rooted plants
Excellent companion plant with similar care requirements and compatible growth habits
Common Diseases
Nutrient Deficiency (Iron/Macronutrient)
Yellowing or pale leaves, stunted growth, loss of coloration in new growth
Increase fertilizer dosing with all-in-one or targeted supplements; ensure adequate light and CO₂ for nutrient uptake
Algae Overgrowth on Leaves
Green or brown algae coating leaf surfaces, reduced photosynthesis, plant vigor decline
Reduce light duration to 8-10 hours daily, increase water changes, add algae-eating fish or shrimp, improve water flow
Stem Rot (Poor Water Quality)
Mushy or blackened stems, leaf loss, foul odor from substrate
Perform 30-50% water change, improve substrate aeration, reduce organic waste, trim affected stems and replant healthy portions
Slow Growth (Low Light/Nutrients)
Minimal new leaf production, weak stems, pale coloration
Increase light to 30-150 PAR, add comprehensive fertilizer, ensure stable water parameters and adequate CO₂
